Abstract

Process for the preparation of ferric chloride from dilute hydrochloric acid, which consists in first of all making a dilute solution of ferrous chloride by reaction with iron and then chlorinating this solution in the presence of recycled ferric chloride and finally in decompressing the solution which has just been chlorinated to evaporate off water. This process yields ferric chloride which can be employed directly as a flocculating agent for water treatment.
